[Imaging of pediatric urinary tract malformations: a series of 32 cases].

PURPOSE: To determine the incidence of pediatric malformative uropathies and to point out the radiological aspects.

MATERIAL AND

METHODS

Exploratory studies of 32 cases of malformative uropathies were assessed between January 1998 to June 1999 in the Radiology Departement of Gabriel Touré Hospital of Bamako. Patients aged from 3 days to 15 years underwent sonographic and radiological examinations.

RESULTS

The sex ratio was 4 males to 1 female. The main findings were: prune belly syndrome (6 cases), posterior urethral valves (13 cases), bladder exstrophy (3 cases), renal ectopy (6 cases), ureterocele (1 case), hypospadias (1 case), megauretere (1 case) and pyelo-ureteral junction syndrome (1 case). Radiological signs were mainly related to hydronephrosis and bladder lesions.

CONCLUSION

Malformations of the urinary tract are frequent in daily practice. Imaging plays a key role in the assessment and diagnosis.
